Can you eat watermelon if you have tonsillitis?
Generally, patients with tonsillitis can eat watermelon, as long as they do so in moderation. The detailed explanation is as follows:

Patients with tonsillitis may consume watermelon because its properties align well with the body's needs during illness. Watermelon has a very high water content, which helps quickly replenish fluids lost due to inflammation and alleviates discomfort caused by dryness and pain in the throat, making swallowing easier. It also contains nutrients such as vitamin C that can help enhance local immunity. Its sweet, cool, and refreshing taste can soothe irritated throat mucosa and improve appetite, preventing inadequate nutrition intake due to pain-induced food avoidance. However, consumption should be moderate to avoid excessive coldness that might irritate the gastrointestinal tract.
Maintain good oral hygiene by rinsing the mouth with warm salt water after meals to reduce bacterial growth from food residue. Follow a light and soft diet, choosing easily swallowed foods like porridge or well-cooked noodles, and avoid spicy, fried, or overly hot foods. Ensure adequate rest, avoid staying up late and overusing the voice, allowing the throat sufficient time to recover. Keep indoor humidity at a comfortable level and ventilate regularly to minimize irritation from dry air. Seek medical attention promptly if symptoms worsen or if fever develops.
